title: Prevalence of juvenile fibromyalgia syndrome in an urban population of Turkish adolescents: impact on depressive symptoms, quality of life and school performance.
abstract: BACKGROUND
  Juvenile Fibromyalgia Syndrome (JFMS) is a chronic health condition characterized by widespread musculoskeletal pain and multiple tender points (TP). The objective of this study was to determine the prevalence of JFMS in the urban population of Samsun and to determine the impact of JFMS on depression symptoms, school performance and quality of life (QOL).
  
  
  METHODS
  A cross-sectional study was conducted in 1109 children (mean age (14.8 ± 2.0) years old). A questionnaire was applied to the children and a medical examination including TP was performed. Yunus and Masi's criteria were used for diagnosis of JFMS. The children with JFMS were compared with an age and sex matched non-JFMS group. Depression was assessed with Children's Depression Inventory (CDI) and QOL was evaluated with Pediatric Quality of Life Inventory 4.0 (PedsQL4.0).
  
  
  RESULTS
  Sixty-one (5.5%) (13 boys and 48 girls) of 1109 children met the diagnostic criteria of JFMS. While PedsQL scores of children with JFMS were lower than the non-JFMS group for physical, emotional, social, school functioning and total score (P = 0.001), CDI total score was higher in the JFMS group than in the non-JFMS group (P = 0.001). The JFMS group reported more school absences (P = 0.001) and the average school grade was lower in the JFMS group than in the non-JFMS group (P = 0.03).
  
  
  CONCLUSIONS
  The prevalence of JFMS is high in school age children. Since JFMS is a common problem of childhood, early diagnosis and identification of the disorder and more comprehensive and successful treatment approaches with appropriate psychological assistance may prevent more complex and severe problems in adulthood.
